"After these things he left Athens and went to Corinth, and he found a Jew named Aquila, a native of Pontus, having recently come from Italy with his wife Priscilla, because Claudius had commanded all the Jews to leave Rome.  He came to them, and because he was of the same trade, he stayed with them and they were working, for by trade they were tent makers.  And he was reasoning in the Synagogue every Sabbath and trying to persuade Jews and Greeks.  But when Silas and Timothy came down from Macedonia, Paul began devoting himself completely to the Word, solemnly testifying to the Jews that Jesus was the Christ.  But when they resisted and blasphemed, he shook out his garments and said to them, 'Your blood be on your own hands!  I am clean.  From now on I will go to the Gentiles.'  Then he left there and went to the house of a man named Titius Justus, a worshiper of God, whose house was next to the synagogue."

Here we see the concept of best practice.  Paul says that he becomes a slave to the slaves...  That is what he is doing here.  He is giving up his rights in order to reach people for Christ.

He tries to reach the tent makers by having a trade. 

He tries to reach the Jews by devoting himself to the Word.

He tries to reach the Gentiles by living next door to the synagogue.

This is sacrifice, and it is effective.  It works.

What will you do to see Christ be realized in your area?  What is sacrifice to you?
